Sorry, this item is no longer available.

  • Network connected via Ethernet/LAN
  • Free web storage for data viewing & archiving
  • Warning alerts via email or text
  • Temperature and Humidity Sensor
  • Holds up to 8,000 data set recordings
  • Sensor Range from 32 to 122°F (0 to 55°C) and 10 to 95%RH

With built-in Ethernet or Wi-Fi, a TR-700W Series logger will measure critical temperature and humidity data in the warehouse, prep area, lab or on the factory floor and stay connected. These new TR-700W Series loggers connect into your existing LAN with a wired or wireless connection and provide real-time data viewing and archiving within your network or in the cloud.

  • Select a Wi-Fi unit (ends in ÐAW) and choose from models with two temperature inputs (TR-701), temperature and humidity (TR-702), or high accuracy temperature and humidity (TR-702-H).

    If a wired connection is preferred, select an Ethernet unit (ends in ÐNW). The same product configuration exists with dual channel temperature, temp & humidity, and temp & humidity with high accuracy. Each logger includes an AC power adapter and internal CR-2032 coin cell battery for data backup if power is lost.

    Once connected to your LAN, you can configure warning emails to your mobile devices, change settings through your browser, set auto data downloads, export for analysis, or store the data to your FTP site or to the free T&D WebStorage Service.

    With data stored to the T&D WebStorage Service, you can view data in real-time, set groups and custom views, report archived data to T&D Graph software, and share with all users and devices with active browsers. You'll pay a monthly fee with most logging systems, but not with ThermoWorks. Web storage is free up to 20MB.

    Looking for local alarms with blinky lights and buzzers? All TR-700W Series loggers include alarm-enabled contacts for connecting an external device when limits are exceeded. Connect an audible alarm or LED light so your staff knows when to check the conditions.

    With a TR-700W Series logger everything is included in the price: software, connection cable, AC adapter, and ThermoWorks technical support!

    T&D Graph & Data Analysis Software

    The newly designed software "T&D Graph" gives you greater management and analyzing power for dealing with the recorded data (TRZ format) collected from TR-700W Series loggers.

    T&D Graph allows you to read larger numbers of recorded data files (TRZ format) into the same graph, merge data, view and save data various ways. It can be downloaded free of charge here.

    This versatile graph tool not only allows the user to directly access data stored in the WebStorage Service, but the user can also specify conditions such as time period for which data to view and analyze.

    It is also possible to sample and filter data, add memos and write comments directly on the graph, as well as, save data to CSV Format for use with common spreadsheet software.
